Brian Mastenbrook discovered that rails, the MVC ruby based frameworkgeared for web application development, is prone to cross-site scriptingattacks via malformed strings in the form helper.

For the stable distribution (lenny), this problem has been fixed inversion 2.1.0-7.

For the oldstable distribution (etch) security support has beendiscontinued. It has been reported that rails in oldstable is unusableand several features that are affected by security issues are broken dueto programming issues. It is highly recommended to upgrade to theversion in stable (lenny).

For the testing distribution (squeeze) and the unstable distribution(sid), this problem has been fixed in version 2.2.3-1.

We recommend that you upgrade your rails packages.
